Smallest Scientific Calc Available?

Ok, anyone know what the smallest scientific calculator currently available is (Casio or otherwise)?
I used to have a CFX-400 watch which was the ultimate, but it died many years ago and they are now ridiculously collectable (read=expensive)
Something credit card sized would be nice, like those credit card solar 4 function jobs, but I want scientific.

Casio made a nice small Scientific Calculator in the 1985 era the FX-98 was a Credit Card sized Solar Scientific Calculator. Radio Shack sold many of these OEM under their banner EC-4009 model #. I wish I would have bought one of these when my TI-35 started bouncing Keypad fault! My TI-35 keypad bounced worse after it sat unused for a while Tarnish on contacts. I have an old TI-25X Playing Card sized 4.2" x 2.6" x .4" Solar Scientific Calculator I bought 10 years ago to replace a TI-35 with a bouncing Keyboard. It is still a nice little Scientific Calc to put in the shirt pocket. The keypad has never bounced on it. I now have a FX-991MS sVPAM that I use for a lot of my number crunching. I have a FX-7400 and 9750 also I use the FX-9750 a lot the 7400 was my 1st Graphing Calc.

I had one of those radio shack minis. loved that thing. I even modified it with a slide switch an button cell so it wold work in low light. lost that little jewel 0 years ago and have been trying to find another. I found a kenko kk-1006 that looks like the kadio 1006 except it has a cover tha makes it thicker. I bought it over ebay and tried to get more but couldnt. I think you can get them from kenko but yo got to buy about 3000.

Why Casio discontinued the fx-98, it is really great, reliable and fits nicely in your shirt pocket... is there any possibility to demand Casio to sell again the fx-98 since a lot of things that were used in the eigthies are back nowdays...
